Abstract
In a method for producing a heat sink, a semifinished product of a first metal material is placed into a die and a material layer of a second metal material of a higher thermal conductivity than the first metal material is releasably connected to a pressure surface of a punch. The punch is brought into contact via the material layer with the semifinished product in the die. The heat sink is formed by pressing the first metal material of the semifinished product by the punch through openings of the die fins of the heat sink are formed and into a peripheral rebate of the punch a peripheral side wall of the heat sink, wherein the material layer is connected over its entire surface to the first metal material of the semifinished product. The punch is released from the material layer, and the heat sink is ejected from the die.
